Abstract: The invention is directed to a blow molded article. The article comprises at least three layers wherein layer A comprises polymer, layer B comprises a foam composition comprising high density polyethylene having a quotient of melt strength and apparent viscosity>2 cN/k.Pa.s and layer C comprises polymer wherein the layer comprising the foam composition is enclosed between two layers A and C and wherein the melt strength is determined as described in ISO 16790:2005 and the apparent viscosity is determined as described in ISO 11443:2014 and wherein the foam composition is produced with a physically blowing agent.

Abstract: The invention is directed to HDPE having a quotient of melt strength according to ISO 16790:2005 and apparent viscosity according to ISO 11443:2014 (melt strength/apparent viscosity)>2 cN/k·Pa·s and ≤30 cN/k·Pa·s. In a preferred embodiment, HDPE with an Ml in the range between ≥0.1 and ≤10 a density in the range between ≥935 and ≤970 kg/m3 a gel fraction less than 5% and an elasticity (ratio of G′/G″ at 0.1 rad/sec) between ≥0.6 and ≤10 is obtained by chain branching HDPE with an Ml in the range between ≥10 and ≤100 a density in the range between ≥935 and ≤970 kg/m3 and an elasticity (ratio of G′/G″ at 0.1 rad/sec) between ≥0.01 and ≤0.2.
